I have seen this good EMI calculator at http://emicalculator.net/ on WordPress site. can anyone please tell me or guide me on which tool / plugin is used to create this first page.
The best way to check which plugins are being used on the site is to go through the source code until you find the plug in. In Google Chrome if you right click and click on 'inspect element', then it should bring it up at the bottom of the screen.
